RAYNHAM — A Raynham Army sergeant who survived the blast of a 200-pound improvised explosive device last year has an optimistic outlook on his recovery from a severe leg wound.

Brandon Korona, who is undergoing treatment at Walter Reed Hospital in Bethesda, Md., said on Sunday that he is in high spirits after going through another surgery in February, as part of a lengthy treatment process. Korona, 22, said that the odds are in his favor that he will not have go through the amputation of his left leg or foot.

“Everything is going well,” Korona said. “I had another surgery to use my heel. They are working right now to just get me mobile again. I’m still working toward avoiding amputation. But that’s slowly becoming less of an option. I’m healing up better.”

Korona, who took a trip back home to Massachusetts over the weekend, said he’s glad that the often monotonous treatment plan he’s undergoing is now yielding results.

Korona also had fun last Tuesday afternoon when members of the Boston Celtics and Red Sox paid a special visit to him and the other patients at the military medical center. Korona said he got to hang out with the likes of point guard Rajon Rondo, second baseman Dustin Pedroia, catcher David Ross, first baseman Mike Napoli, outfielder Jonny Gomes and designated hitter David Ortiz.

“I got to sit and hang out and talk with them,” Korona said. “They are all really down to Earth and relaxed people. They actually care about what’s going on. I was ecstatic about talking to Pedroia. That was a good time. I just talked to him about who I really was and who he really was, and what he thought about the cause. He was just really supportive. … He knows that soldiers have it rough.”

Korona said that Pedroia and the others expressed words of gratitude.

“He told me, ‘We all say thank you,’ and he was grateful for the chance to talk to us, to get to know some of the soldiers who were injured fighting for the country,” Korona said.

Korona said that his mother, who has moved to the Washington, D.C., area to be with him throughout his treatment and recovery process, also got to take part in the visit by the players. They took pictures with the athletes and got to see the Red Sox’s three most recent World Series trophies.

“It was a break from the normal monotonous everyday physical therapy appointments,” Korona said. “It was something different and something that I really got to enjoy. It was great for my mom there with me. She loved it, too. She took full advantage of it.”

Korona survived the devastating blast of a 200-pound IED in the Paktika province of Afghanistan on June 23, 2013. The blast took the life of a fellow soldier, Javier Sanchez, of Greenfield, Calif., who was 28.

During an interview last year with the Taunton Daily Gazette, Korona, then a corporal, said Sanchez was “a good friend and a really good guy.” Korona also said that he wished he could still be with the soldiers he was serving with.

“I wish I was still there with all my brothers,” Korona said in the 2013 interview. “I’m proud of what I did in the Army, doing something and helping people. I’ve grown to 20 times the man I was.”

Korona said that he now has his eyes set on a March, 21, 2015, Army discharge date and a future as a military contractor.

“I’m looking to possibly do electrical engineering in college, and working private sector or civilian side,” Korona said. “I’m trying to get a job in something military contractor or military development … on the civilian side developing things and working on stuff for future soldiers, so their lives are better.”

Korona said he’s happy to have the support of his family, friends and loved ones.

“Everybody has been great and helpful,” he said. “Everyone has just been really supportive and caring about everything, and making sure they are involved and know what’s going on with my future and checking in. It’s been awesome.”
